Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in the Core component of Google Chrome before version 155.0.8059.39. It allows a remote attacker to execute arbitrary code outside the sandbox by tricking a user into visiting a specially crafted HTML page.

Detection Guidance

This vulnerability is specific to Google Chrome versions prior to 155.0.8059.39. Detection involves checking the installed Chrome version. On Linux, run: google-chrome --version. On Windows, check via Control Panel or run: wmic product where name='Google Chrome' get version. If the version is below 155.0.8059.39, the system is vulnerable.

Impact Analysis

An attacker could exploit this to run malicious code on your device, potentially stealing data, installing malware, or taking control of your system. It may also allow bypassing browser security sandbox protections.

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code outside the sandbox via crafted HTML pages, which could lead to unauthorized data access or manipulation. Such risks may impact compliance with GDPR (data protection) and HIPAA (health data security) by potentially exposing sensitive information or violating integrity requirements.
